SOLDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 247,267, dated September 20, 1881.

Application filed July 2, 1881. (No model.) i

To all whom it may concern: 7

Be it known that I, JOHN OLOUGHLIN, of Baltimore city, State of Maryland, have invented certain new and useful Improvements in Soldering-Machines; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the machine, partly in section. Fig. 2 is a plan of the solder well and iron. Fig. 3 is a central vertical sectional view of the latter; and Fig.4 is a plan of the lower clamping-disk.

My invention relates to that class of soldering-machines designed to solder the heads to the bodies of cylindrical cans, and to that subdivision of said class in which the soldering is done on the outside by revolving the can with its head-seam immersed in a bath of molten solder.

My said invention will be first described, and then pointed out in the claims.

In the drawings, A is a frame or support, mounted at a suitable height above the floor to permit of the manipulations of the operator in soldering the cans, and to it are secured supports a, in which is pivoted at 0 the frame 0. The blocks a, which carry the frame-pivots, slide vertically in slots in the supports a, and are made vertically adjustable by means of screws B.

In the frame 0 is mounted, in bearings E, a shaft, D, carrying a pulley, G, for a drivingbelt or a crank, 9, whereby the shaft is caused to revolve. Between a collar, F, and the end bearing is coiled a spring, f, serving to thrust the shaft longitudinally within the frame 0, and on the end of the shaft is secured a disk, d. Acollar, n, is secured upon the shaft, with which the upper end of a bell-crank lever, N, pivoted at 0, engages. A wire, 0, connects the other end of the lever with a treadle, 1). It will be understood that upon depressing thetreadle the shaft D is made to slide endwise within the frame 0 and against the resistance of the spring f, which latter, when the treadle is released, returns the shaft to its normal position, as shown. In the other end of the frame 0 is mounted, in bearings I, a shaft, H, having a collar, 1', that abuts against the inner bearing. Ascrew, J, serves to thrust the shaft inward, and a disk, h, is secured upon the end of the shaft. This disk is provided with a central boss or ring, it, which is accurately of the size of the head opening of the can. The two disks d and h are preferably made removable from their shafts, so that their positions may be reversed, the disk-b being then secured upon the shaft H. Rods K are attached to the frame 0, and, passing through bearings in bars M, are connected with a treadle, m. A spring, k, on each rod is coiled between the lower bearing and a collar, l, and serves to raise the frame when the treadle m is released.

Q, is the solder-well, having at one side the soldering-iron which is provided with a rim, 1, and flange 1, adapted to fit against the head-flange of the can which rests and turns against the surface r. A hole, r, in the rim 1'' connects the iron with the well. The iron projects downward, as at 8, into a casing, q, and receives the blast from a burner, S, or the heat from a charcoal fire made in the casing, and a pipe, R, serves, in the latter case, to cause a draft and carry oit'the products of combustion; or, if a burner be used, it subserves a similar end and prevents the flames from being driven back and out at the front of the casing g.

In operation the treadle p is depressed, retracting the disk d, and the can is placed between the disks, the boss It being made to enter the hole in the can-head. The treadle pis then released and the disk 01 advances, clamping the can with its axis in accurate alignment with the shafts H and D. The treadle m is then depressed, causing the frame to tilt, and bringing the head seam down upon the iron and immersing its lowest point in the molten solder. The can is then caused to turn by means of the crank g ora belt upon the pulley Gr, bringing every point of the seam into the solder and into contact with the iron. The treadle m is finally released, the treadle p is depressed, and the can is removed. Its other head seam is then soldered on a similar machine having the positions of the clampingdisks reversed.

Referring, now, to certain features of construction, the advantages of which may well be more particularly pointed out, I would state that an important result attends the use of the revolving can-holder having the bossed disk It, as the axis of the can is held rigidly in alignment with the axis of the shafts and all portions of the seam bear equally upon the iron, The latter, too, touches the seam throughout its whole extent, as the hole 1" is made in the rim 0", and not in the base r.

The solder-well is open, and the dross may be brushed off from time to time, none of it by any chance being allowed to come upon the iron.

The pipe R obviates what has heretofore, in this class of machines, been a source of serious annoyance, as it conducts the flames and products of combustion away, and they do not, as heretofore, flare out at the front of the casing and over the hands or clothingof the operator.

The screw J and the vertical movement of the journals of the frameG admit of the nicest adjustment of the can-seam to the iron.

What I claim is- 1. In a can-solderin g machine, mechanism, substantially as described, for revolving the can and for bringing its seams down into a solder-bath,in combination with a flanged and curved soldering -iron, communicating below the surface of the solder with an open-topped well.

2. In combination with the solder well and iron, the tilting frame and clamping-disks, one of the latter being provided with a central boss or projection adapted to enter and fit within a hole in the can-head, as set forth.

3. In combination with the tilting frame 0 and shafts carrying the bossed disk It and disk 01, the lever N, wire 0, and treadle p, as set forth. a

4. In combination with the frame 0 and clamping-disks, the solder well and iron, and treadles mp, adapted, by means of intermediate connections, to tilt the frame and separate the disks, as set forth.
